A week late but still negative😫

So I’ve tested twice in past week with cheap dollar store tests and they’ve been negative. I’m a week late today. I’ve always had irregular periods but the past four months I’ve been right on track with the app! So now I’m just wondering if my body is just reverting back to being irregular or I need to try a different test? When did you get a blood test? I’m feeling so frustrated and disappointed. I’ve even been bloated, some light cramping and heaviness in my uterus the past couple weeks, upset stomach a couple times (which is rare for me), and then tonight out of the blue I developed two canker sores on my gums (which I read can be a symptom..and it’s been forever since I had one and normally they’re on my cheek not my gums??) I’ve also been Soo tired which is normal for me but I remember feeling this tired with my last pregnancy. Also (maybe TMI) I have had TONS of clear egg white discharge the past week but not spotting (but I already ovulated??) I figured I would wait a couple more days and test again. What do you all think??
